Description

PATENT APPLICATION

PIANO MICROPHONE APPARATUS

CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure claims the benefit of U.S. Provisional Application Serial No. 60/943,915 filed June 14, 2007 and entitled PIANO MICROPHONE APPARATUS, which is fully incorporated herein by reference.

FIELD

This disclosure relates generally to microphones and microphone stands. More specifically, this disclosure relates to a piano microphone apparatus configured to sit inside of a piano.

BACKGROUND

Miking a piano can be a difficult task. In general, it is desirable for the microphone(s) to be directed at strings inside the piano. Some microphones may be mounted on external free-standing mic stands, then extended into the piano for miking. However, these stands may be visually unacceptable and may not allow the lid of the piano to close. Other microphones may be mounted on the edge of a piano with the lid opened, and are pointed inside. Here, again the piano lid may not able to close. Some pianos use miniature microphones mounted on suction cups inside the piano. The suction cups may be mounted to the piano frame, which may allow the lid to be opened and closed; however, the position of the microphones relative to the piano may result in poor recording. In some cases, the suction cups may be mounted directly to the inside surface of the lid for miking with the piano lid closed. While this may allow the microphone to be positioned at a desired location over the strings, the lid of the piano may not be opened without changing the position of the microphone. Further, the suction cups may become detached and fall onto the piano strings or inside the piano during a performance.

Protruding members 304A and 304B may be flexible in construction and may be configured to bend, allowing microphones 302A and 302B to be adjustably positioned in a specific location within the inside of the piano. Protruding members 304A and 304B may be configured to include a wire (reference numeral 525 as shown in Figure 5) to provide power and/or signal to microphones 302A and 302B. For example, protruding members 304A, 304B may be hollow in construction, thus allowing the wire to pass therethrough. Protruding members 304A, 304B may be operatively connected with outer members 306A, 306B and/or inner member 308. In some embodiments, protruding members 304A, 304B may be adjustably positionable about the outer and/or inner members. In some embodiments, a track may be included that allows the protruding members to slide along either the outer and/or inner members. Once positioned, protruding members may be secured into place using a securing mechanism, including, but not limited to, clamps, screws, etc. Protruding members 304A, 304B may also be configured to rotate around either of the outer 306 and/or inner members 308.

Protruding members 304A, 304B may be affixed to inner member 308. Inner member 308 may act as a conduit for the wire and may be configured to deliver the wire to each of the protruding members 304A, 304B. Inner member 308 may also act as a housing for circuitry connected to microphones 302A and 302B and/or other electronic equipment outside the piano microphone apparatus. Inner member 308 may be operatively connected with outer members 306A, 306B using a variety of different arrangements. For example, inner member 308 may be connected with each of the outer members using a number of different arrangements, including but not limited to, screw-clamps, threaded rod, and/or any other suitable arrangement. Each of outer members 306A, 306B may be extended either towards or away from piano interfaces 310A, 310B. Once the correct position has been established outer members 306A, 306B and inner member 308 may be secured in place. In some embodiments, outer members 306A, 306B may be configured to move (e.g., slide) over the outside of, or inside of inner member 308, for example, in a telescoping arrangement. The adjustments provided by the inner and outer members allow apparatus 300 to fit pianos of varying sizes and widths.

Referring now to Figure 4, another exemplary embodiment of a piano microphone apparatus 400 is shown. In some embodiments, outer members 406A, 406B may connect inner member 408 with piano interfaces 410A, 410B. At least a portion of each of piano interfaces 410A, 410B may be configured to rest on the sides 415A, 415B of the case 409 of a piano as shown in Figure 4. In some embodiments, piano interfaces 410A, 410B may be thin enough to allow the lid of the piano to open and close without disturbing microphone apparatus 400 but strong enough to hold the apparatus in position. In some embodiments, piano interface 410A, 410B may include fixed or rotating brackets, flanges, L- shaped members, or any other mechanism capable of holding piano microphone apparatus 400 within the piano. In some embodiments, each piano interface 410A, 410B may be configured to rest in a substantially flush position with a side of the piano. Also, piano interfaces 410A, 410B may be secured to the piano using a variety of different techniques, including, but not limited to, screws, nails, rivets, etc. Each piano interface may be constructed out of a variety of different materials, including, but not limited to, metals and polymeric materials. In some embodiments, piano interfaces 410A, 410B may further include other securing mechanisms such as rubber or cloth, which may act to minimize movement of the apparatus 400 while minimizing any damage to the piano. Of course, various other arrangements are envisioned without departing from the scope of this disclosure.
